Types. Holotype: male ( CNAN-T01041 ) from San Sebastían del Oeste , road to Cerro de “La Bufa” (20.7495°N, 104.8283°W, 1681 m), Jalisco, Mexico, 28.VI.2016, D. Guerrero-Fuentes, G. Contreras-Felix, G. Montiel-Parra & L. Olguín leg. GoogleMaps Paratypes: 2 ♀ ( CNAN-T01042 ), same data as holotype GoogleMaps .

Additional material examined. MEXICO, Jalisco: 3 ♀ (CNAN-Ar 011161), same locality as types, 12.IX.2017, D. Guerrero, G. Montiel, R. Paredes & I. Salgado leg. ; 2 ♁, 2 ♀ (CNAN-Ar 011162), same locality as types, 14.VI.2018, D. Guerrero, G. Contreras & J. Arreguin leg.

Etymology. The epithet is a noun in apposition, and refers to the faunus in the Roman mythology, a fantastic creature who lived in the woods, the usual habitat of Anicius species.

Diagnosis. This species resembles A. cielito sp. nov. in general color pattern ( Figs 7–8 View FIGURES 1–12 ), but we can distinguish A. faunus from the remaining species of Anicius by the male genitalia: A. faunus has a needle-shaped embolus, similar to A. dolius Chamberlin and A. maddisoni sp. nov., but differs from those because the embolus is straight or less curved ( Figs 66 View FIGURES 60–71 , 75 View FIGURES 72–77 ), and TL has a triangular retromarginal crest ( Fig. 67 View FIGURES 60–71 ). The female has brown leg I with yellow tarsus ( Fig. 47 View FIGURES 42–47 ).

Description. Male (holotype CNAN-T 01041). Total length: 4.50. Prosoma: 2.10 long, 1.60 wide and 0.70 high. Opisthosoma: 2.40 long, Eye field: 1.00 long, anterior width 1.40, posterior width 1.40. Cheliceral length 0.50. Length of leg segments: I 1.50 + 0.80 + 1.00 + 0.90 + 0.50 = 4.90; II 1.00 + 0.50 + 0.70 + 0.60 + 0.40 = 3.20; III 1.00 + 0.50 + 0.50 + 0.60 + 0.40 = 3.00; IV 1.20 + 0.50 + 0.80 + 0.80 + 0.40 = 3.70.

III: Fm d 1-1-1, p 0-0-2, r 0-0-1; Tb v 0-0-1, p 0-1-0, r 0-1-1; Mt p 0-0-2, r 0-0- 2. IV: Fm d 1-1-1, p 0-0-1, r 0-0-1; Tb v 1 -0-2, p 0-1-0; Mt pl 0-1-2, r 0-0-1. Body coloration: specimens in alcohol turn to a brownish yellow color with metallic scales. Carapace dark brown, with a white band of setae around the lateral margins of the carapace and across the clypeus ( Figs 42, 44 View FIGURES 42–47 ). Abdominal white bands followed by one pair of white spots and a pair of dark spots ( Figs 7 View FIGURES 1–12 , 42, 44 View FIGURES 42–47 ). Chelicera: triangular and brown, as described for the genus. Thoracic area: as described for the genus ( Figs 43, 46 View FIGURES 42–47 ). Legs: I dark brown, stouter and longer than the other legs; II–IV thin, pale-yellow with darker spots ( Figs 7 View FIGURES 1–12 , 42–44 View FIGURES 42–47 ). Opisthosoma: dorsally deep dark brown ( Figs 42–44 View FIGURES 42–47 ). Palp: Embolus granulated ( Fig. 75 View FIGURES 72–77 ), large and thin, slightly curved at 75° ( Fig 66–67 View FIGURES 60–71 , 75 View FIGURES 72–77 ); TL rectangular with a triangular crest, bulb oval, longer than wide ( Figs 66–67 View FIGURES 60–71 ); RTA hook-like.

Female (paratype CNAN-T 01042). Total length: 4.30. Prosoma: 1.70 long, 1.30 wide, 0.70 high. Opisthosoma: 2.60 long. Eye field: 0.70 long, anterior width 1.00, posterior width 1.00. Chelicera length 0.40. Length of segments: I 0.80 + 0.40 + 0.55 + 0.40 + 0.30 = 2.60; II 0.60 + 0.35 + 0.40 + 0.35 + 0.30 = 2.00; III 0.60 + 0.40 + 0.40 + 0.30 + 0.30 = 1.95; IV 0.80 + 0.40 + 0.50 + 0.40 + 0.35 = 2.55. Leg spination: I: Fm d 1-1-1, p 0-0-2; Tb v 2-2 -2; Mt v 0-2- 2. II: Fm d 1-1-1, p 0-0-2; Tb v 1-1 -2, p 0-0-1; Mt p 0-1-1, r 0-0- 1. III: Fm d 1-1-1, p 0-0-2, r 0-0-1; Tb v 0-0-2, p 0-1-1; Mt pl 0-0-2, r 0-0- 2. IV: Fm d 1-1-1, p 0-0-1, r 0-0-1; Tb v 1 -0-1, p 0-1-0; Mt p 0-0-2, r 0-0-1. Differences with the male: Legs: I stout and slightly longer than IV, dark brown with yellow tarsus ( Figs 45–47 View FIGURES 42–47 ); II–IV yellow without markings ( Fig. 45 View FIGURES 42–47 ). Palp: yellow. Opisthosoma: noticeably wider than in male ( Figs 45–47 View FIGURES 42–47 ). Epigyne: simple, CD with the convergent-divergent pattern, and with three loops ( Figs 84–85 View FIGURES 78–89 ).

Variation. Males (n = 3). Total length: 3.60–4.60. Prosoma: 1.70–2.10 long, 1.00–1.60 wide. 0.70–1.00 high. Opisthosoma: 1.90–2.50 long, 1.10–1.20 wide. Ocular quadrangle: 0.80–1.00 long, anterior width 1.00–1.20, posterior width 1.00–1.20 wide. Females (n = 7). Total length: 3.50–4.30. Prosoma: 1.60–1.80 long, 1.30 wide. 0.70 high. Opisthosoma: 1.70–2.60 long, 1.60–1.90 wide. Ocular quadrangle: 0.70 long, anterior width 1.00, posterior width 1.00. Some females (n = 4) do not have the medial longitudinal darker band well-defined. One male has a single-cuspid retromarginal tooth instead bicuspid, visibly torn due aging.

Natural history. Specimens were found during the day wandering on trees in pine-oak forest ( Fig. 21 View FIGURES 18–23 ).
